Subject: [PATCH net-next v3 02/14] net: sfp: derive interface mode from ethtool link modes
Date: Wed, 11 Dec 2019 10:55:59 +0000	[thread overview]
Message-ID: <E1iezex-0002xl-GI@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20191211104821.GB25745@shell.armlinux.org.uk>

We don't need the EEPROM ID to derive the phy interface mode as we can
derive it merely from the ethtool link modes.  Remove the EEPROM ID
argument to sfp_select_interface().
